The Holland Tunnel: The Holland Tunnel is a tunnel under the Hudson River that connects Manhattan to Jersey City, New Jersey. The tunnel opened in 1927 and was the first subaqueous tunnel in the world designed for automobile traffic. The tunnel is a National Historic Landmark and is also one of the first ventilated tunnels in the world. The ventilation system was needed to clear out vehicle exhaust and carbon monoxide generated by the automobiles passing through. Almost 35 million vehicles pass through the Holland Tunnel each year.
